SetTimeout() not working

[JLeger91]

The screen looks like the above and the background bogs up and down. A lightning flash can happen and tests successfully.
However, the SetTimeout() timer that has lightning flash every now and then is not working.


Here is where the animate() function happens and where the timeout is called and it doesn't work.


Here is where the lightning effect is coded and it works successfully if there is no timeout.

Hi there,
So one thing to keep in mind:
setTimeout only fires once. after the given delay amount.

What you are looking for is setInterval

The problem is that neither SetInterval nor SetTimeout fires at least once. They simply aren't working.

Is your code even getting to the point where setTimeout/setInterval is firing off?

Yes it is. Because it gets to code past that; just seems to skip right over the SetInterval code.

If I use SetTimeout or SetInterval, and I put a console.log('Hello world!')
Then I notice in the console that the message in fact appears after set number of seconds, and then a number on the left of 'Hello world!' keeps increasing rapidly with no end.

Except if I use a doOnce variable, then it only fires once.
However, the lightning effect still doesn't happen.
Interestingly, it enters and exits the function but just doesn't do the stuff.
Now it seems that it does in fact enter all parts of the lightning function but I can't see the alpha updating visually.
So all of the variables are updating but I just can't see the changes visually.
I got it working. I simply moved the ctx.fillStyle and ctx.fillRect in front of the setInterval function.

Okay, so the problem now is that the lightning flash code repeats over and over again. That might be internal to the lightning_flash function though. Maybe what I need is a doOnce of some sort?

Perhaps I should leave it alone for now and have just one lightning flash.
